Performance Co-Pilot (PCP) is a framework and set of services for supporting system-level performance monitoring and performance management. It provides a unifying abstraction for all of the interesting performance data in a system, and allows client applications to easily retrieve and process any subset of that data using a single API. A client-server architecture allows multiple clients to monitor the same host, and a single client to monitor multiple hosts. Archive logging and replay are integrated so that a client application can use the same API to process real-time data from a host or historical data from an archive.

ZABBIX is an enterprise-class distributed monitoring solution designed to monitor and track performance and availability of network servers, devices, and other IT resources. It supports distributed and Web-based monitoring, auto-discovery, real-time monitoring, SLA assurance, trending, and more.

Hypersocket is a cross-platform Hybrid SSL VPN solution built for all types of remote access scenarios. Powerful, yet simple to use, Hypersocket uses a single installed client to provide access to any number of network resources. Its powerful granular access means you can have fine-grained control over your entire network and remote users. Accessed through a secure HTTPS port, the Hypersocket client provides access to any number of host/port combinations, all assigned server-side by the Administrator through roles. The Administrator is able to configure the server through a Web portal on the same HTTPS port.

The ServerStatus application will display a window that shows the status of a list of servers, NAS, routers, etc. ServerStatus will 'ping' each server/network device once per minute to determine if it is 'online' or 'offline'.

Pen is a load balancer for "simple" TCP-based protocols such as HTTP or SMTP.
It allows several servers to appear as one to the outside. It automatically
detects servers that are down and distributes clients among the available
servers. This gives high availability and scalable performance.

DeleGate is a multi-purpose application level gateway or proxy server that mediates communication of various protocols, applying cache and conversion for mediated data, controlling access from clients, and routing toward servers. It translates protocols between clients and servers, converting between IPv4 and IPv6, applying SSL (TLS) to arbitrary protocols, merging several servers into a single server view with aliasing and filtering. It can be used as a simple origin server for some protocols (HTTP, FTP, and NNTP).

Wireshark is a network protocol analyzer, or "packet sniffer", that lets you capture and interactively browse the contents of network frames. It provides a commercial-quality packet analyzer for Unix, and the most useful packet analyzer on any platform.
